M JW Patented May 19, 1931 PATENT OFFICE KORNEL ISSAR, OF DETROIT, MICHIGAN HUMIDIFIER FOR GAS ENGINES Application filed April 3, 1930. Serial No. 441,203.

The object of my invention is to produce a humidifier adapted for introducing moisture into the fuel gases before entering the same into the engine cylinder combustion chambers.

Another object is to produce a humidifier for introducing moisture into the engine fuel gases that is always under direct control of the operator of the engine.

A further object is to produce a gas englne humidifier that can be synchronized with and operated by the carburetor operating mechanism, in a manner for varying the amounts of moisture introduced in the fuel gas directly with the speed of the motor.

A still further object is to produce a special humidifier tank that will disintegrate the water placed therein so that it may be drawn therefrom in a vapor form of uniform density.

A further object is to produce a humidifier for gas engines that is simple in construction, easily and efficiently operated and can be manufactured at a low cost.

These several objects are attained in the preferred form by the construction and arrangements of parts more fully hereinafter set forth,

Similar parts on all drawings are marked by similar numerals or letters.

Fig. 1 is a front view of the humidity tank showing the inlet and outlet passage connections.

Fig. 2 is a top View of the tank as shown in the Fig. 1, showing the relative positions of the various tank openings. V

Fig. 3 isa vertical sectional view taken on the line 3-3 of the Fig. 2 showing the relative position of the operating parts as mounted within the tank.

Fig. 4 is a horizontal sectional view through the tank body taken on the line t-4: of the Fig. 1 showing the construction of the water float and means for attaching the indicator rod thereto. Fig. 5 is an assembled view showing my device as installed in an automobile and connected to the engine with the means for operating and regulating same.

I will now describe more fully the, detailed construction of my device, referring to the drawings and the marks thereon.

In general my device comprises a sealed liquid tank having means for injecting Water therein. The tank is provided with a water indicator float, and inlet and outlet ports covered by suitable valve and shields for preventing water from flowing from either port in a liquid form. The tank outlet port being connected with the engine fuel intake manifold by a pipe line within which is installed suitable operating and regulating valves.

The tank -1- is preferably made of sheet metal, cylindrical in form, closed at the bottom and provided with a cap top 2 tightly fitted and sealed thereon, forming a closed air tight tank. The bottom of the tank l is formed with a threaded opening 3-- therethrough and carries mounted therein a curved funnel tube 4 also threaded at the stem end 5 for engaging the threaded tank opening 3, projecting the tube end -5 vertically within the tank chamber 6 and positioned therein along the centerline of the tank. The funnel tube 4 is securely attached to the tank bottom by the lock nut 7 tightly screwed thereon, and the joint made water tight by the gasket 8. placed therebetween. The funnel tube 4L- is curved at right angles to the threaded stem -5, and formed with an air hell 9 on the outer end thereof, positioned to face the front side of the tank when installed on an automobile. The top end of the stem r 5- is formed with an open spherical valve seat 10 thereon. Mounted on the valve seat 10 is a true hemispherical valve cap -ll, preferably made of light sheet metal, designed and fitted'thereto to maintain a water tight joint with the seat for all positions of the valve cap. On the bottom side of the valve cap 11 is attached a light coil spring 12 which is extended tothe curved portion of the funnel tube -l: and attached thereto by the adjusting screw 13 mounted in the funnel tube wall. The adjusting screw 13 is provided with a lock nut -14 for fixedly retaining same in any adjusted position, the screw -13 providing means for varying the tension of the connected spring 12 on the attached valve cap 11-', and for maintaining a water tight joint With the valve seatl-l, yet sufficiently free to allow an intake of air therethrough-when subjected to engine cylinder vacuum. Within the tank top 2, preferably on the back side of the tank is-mounted a. threaded fill ng plug'tigli fly fitted therein and pro viding means for in]ecting Water w1th1n the tank chamber 6. At the opposite side of the top 2 is formed arr outlet. port 16'- extending through the cap wall and opening into the tank chamberr Mounted within" the outlet port -16? is. a feed pipe 17 securely attached 'to the'top' 2'by V the loeknu :+18-engas h a hre ded b s -19 formedon the tank top concentric with port-+167 Directly beneath the outlet; pom-+16% and-Wit i the tehlah elh s is; mounted a fine screen; cone. filter T2077 securely attached to the insidelwall o f-'cap ;j2-l and pesitioned concentric with he ortg-ewr O tside the 1s filter +20+ implacedahoa e crew; po e filter 21.olf largerdime sions, posl he 1. centric withithehone filter 20:- and also i securely attached to the inside wall of the ca 72%.
